Gold alone found on the sea floor is estimated to be worth $150 trn. But the cost to the planet of extracting it could be severe.

Oceans cover 70 percent of the earth's surface, but only a fraction of the undersea world has been explored.
On this episode of TechKnow, Phil Torres joins a team of scientists on a special expedition to explore and uncover the mysteries at the bottom of the ocean floor.
"What we are doing is similar to astronauts and planetary scientists just trying to study life on another planet," says BethOrcutt, a senior research scientist.
The journey begins in Costa Rica aboard the R/VAtlantis, a research vessel operated by the Woods Hole Oceanographic Institution. From there, Phil gets the chance to take a dive with Alvin, a deep-water submersible capable of taking explorers down to 6,000 metres (20,000 feet) under the sea.
Commissioned in 1964, Alvin has a celebrated history, locating an unexploded hydrogen bomb off the coast of Spain and exploring the famous RMS Titanic in the 1980s.
Alvin and its first female pilot, CindyVan Dover, were the first to discover hydrothermal vents, which are underwater springs where plumes of black smoke and water pour out from underneath the earth's crust. The vents were inhabited by previously unknown organisms that thrived in the absence of sunlight.
After 40 years of exploration, Alvin got a high-tech upgrade. The storied submersible is now outfitted with high-resolution cameras to provide a 245-degree viewing field and a robotic arm that scientists can use to pull samples of rock and ocean life to then study back on land.
But scientists are not the only ones interested in the ocean. These days the new gold rush is not in the hills, it is in the deep sea. For thousands of years miners have been exploiting the earth in search of precious metals. As resources on dry land are depleted, now the search for new sources of metals and minerals is heading underwater.
The NationalOceanic and Atmospheric Administration's national ocean service estimates that there is more than $150tn in gold waiting to be mined from the floor of the world's oceans.
"The industry is moving very, very fast. They have far more financial resources than the scientific community," says Cindy Van Dover, Alvin's first female pilot and Duke University Oceanography Professor.
Seabed mining is still in the planning stages, but Nautilus Minerals, a Canadian mining company, says it has the technology and the contracts in place with the island nation of Papua New Guinea to start mining in its waters in about two years.
What is the future of seabed mining? And what are the consequences of seabed mining for the marine ecosystems? Can science and industry co-exist and work together on viable and sustainable solutions?

Canadian mining company Nautilus Minerals has reached an agreement with the government of Papua New Guinea to begin mining an area of seabed believed to be rich in gold and copper ores, according to the BBC.
Under the terms of the agreement, Papua New Guinea will contribute $120 million to the operation and receive a 15 percent share in the mine.
Environmentalists say the mine will devastate the area and cause long-lasting damage to the environment.
The BBC reports that "the mine will target an area of hydrothermal vents where superheated, highly acidic water emerges from the seabed, where it encounters far colder and more alkaline seawater, forcing it to deposit high concentrations of minerals."
The report continues:
The result is that the seabed is formed of ores that are far richer in gold and copper than ores found on land.
Mike Johnston, chief executive of Nautilus Minerals told the BBC "that a temperature probe left in place for 18 months was found to have 'high grade copper all over it'."
Nautilus announced in April that it had completed its bulk cutter, the first component of its Seafloor ProductionTools system, which will be used to mine the seabed.
Nautilus also approximately 500,000 square kilometres of "highly prospective exploration acreage" in Papua New Guinea, the Solomon Islands, Fiji, Vanuatu and Tonga, as well as in international waters in the eastern Pacific, the company said in a press release.

Deep down, way deep down, there's something stirring - something very, very valuable.
It's a race to the bottom - to the bottom of the oceans. It is Deep Sea Mining. As deep as 5000 metres, maybe more, lie a host of materials critical for modern society, from smartphones to electric cars to green energy. But how can be it be mined without ruining another beautiful, so-far untouched - yet valuable part of our planet?
Joining us on skype from Kingston, JamaicaMichaelLodge, Secretary-General at the International Seabed Authority; from Washington DC, Conn Nugent, ProjectDirector of Seabed Mining Project at the Pew Charitable Trusts; Regan Drennan, Research Assistant at UK Seabed Resource who studies the biodiversity of the ocean floor; Charlotte Middlehurst, a Contributing Editor at ChinaDialogue, focusing on China's growing interest in deep sea mining.

Watch the latest in the Ocean series - What sharks reveal about the state of the Ocean: https://youtu.be/6xz1mxppMhY
The ocean covers 70% of our planet. The deep-sea floor is a realm that is largely unexplored, but cutting-edge technology is enabling a new generation of aquanauts to go deeper than ever before.
Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7
Beneath the waves is a mysterious world that takes up to 95% of Earth's living space. Only three people have ever reached the bottom of the deepest part of the ocean. The deep is a world without sunlight, of freezing temperatures, and immense pressure. It's remained largely unexplored until now.
Cutting-edge technology is enabling a new generation of aquanauts to explore deeper than ever before. They are opening up a whole new world of potential benefits to humanity. The risks are great, but the rewards could be greater. From a vast wealth of resources to clues about the origins of life, the race is on to the final frontier
The Okeanos Explorer, the American government state-of-the-art vessel, designed for every type of deep ocean exploration from discovering new species to investigating shipwrecks. On board, engineers and scientists come together to answer questions about the origins of life and human history.
Today the Okeanos is on a mission to investigate the wreck of a World War one submarine. EngineerBobby Moore is part of a team who has developed the technology for this type of mission.
The “deep discover”, a remote operating vehicle is equipped with 20 powerful LED lights and designed to withstand the huge pressure four miles down. Equivalent to 50 jumbo jets stacked on top of a person
While the crew of the Okeanos send robots to investigate the deep, some of their fellow scientists prefer a more hands-on approach. DoctorGreg stone is a world leading marine biologist with over 8,000 hours under the sea. He has been exploring the abyss in person for 30 years.
The technology opening up the deep is also opening up opportunity. Not just to witness the diversity of life but to glimpse vast amounts of rare mineral resources. Some of the world's most valuable metals can be found deep under the waves. A discovery that has begun to pique the interest of the global mining industry.
The boldest of mining companies are heading to the deep drawn by the allure of a new Gold Rush. But to exploit it they're also beating a path to another strange new world. In an industrial estate in the north of England, SMD is one of the world's leading manufacturers of remote underwater equipment. The industrial technology the company has developed has made mining possible several kilometers beneath the ocean surface.
With an estimated 150 trillion dollars’ worth of gold alone, deep-sea mining has the potential to transform the global economy.
With so much still to discover, mining in the deep ocean could have unknowable impact. It's not just life today that may need protecting; reaching the deep ocean might just allow researchers to answer some truly fundamental questions. Hydrothermal vents, hot springs on the ocean floor, are cracks in the Earth's crust. Some claim they could help scientists glimpse the origins of life itself.
We might still be years away from unlocking the mysteries of the deep. Even with the latest technology, this kind of exploration is always challenging. As the crew of the Okeanos comes to terms with a scale of the challenge and the opportunity that lies beneath, what they and others discover could transform humanity's understanding of how to protect the ocean.
It's the most hostile environment on earth, but the keys to our future may lie in the deep.

Out feature story this week takes us on a rather sobering underwater expedition into the dark world of seabed phosphate mining. The deep ocean floor, admittedly, is not a habitat we generally give much thought to. But in mankind’s quest for resources and mineral wealth, companies have now turned to this relatively unexplored region, and its phosphates they’re after, a resource in relatively limited supply on Earth. Is the supply of phosphates really so limited that it’s worth scraping our ocean bed completely bare? With our global seas, sea life and climate already in serious trouble, this action certainly seems like a bridge too far. Bertus went to see if he could get to the bottom of this matter.

As the demand grows for the metals that power electronics, we may have to look farther and farther for mining opportunities. The next big mining frontier is the deep sea: along the seafloor, mysterious vents shoot scalding hot fluid into the ocean. These vents are a haven for miraculous and unique sea life, but they’re also home to highly concentrated (and very valuable) metals. What happens if we decide that the metals are worth more than the life?

Filipino divers disappear into water as opaque as chocolate milk as they blindly dig in search of gold trapped in muddy sediment. It's risky business: As miners go deeper, underwater tunnels could collapse or the compressor that provides air may fail. Hari Sreenivasan reports on a dangerous venture undertaken by adults and kids.

Science and technology

Seah (unit)

The se'ah or seah (Hebrew:סאה‎) is a unit of dry measure of ancient origin used in Halakha (Jewish law), which equals one third of an ephah, or bath. Its size in modern units varies widely according to the criteria used for defining it.

According to Herbert G. May, chief editor of two classic Bible-related reference books, the bath may be archaeologically determined to have been about 5.75 gallons (22 liters) from a study of jar remains marked 'bath' and 'royal bath' from Tell Beit Mirsim.
Since the bath unit has been established to be 22 litres, 1 se'ah would equal 7.33 litres or 7.33dm3.

In the context of a mikveh, a se'ah can be about twice as much in order to accommodate even the most stringent rabbinical ruling on immersion. A mikveh must, according to the classical regulations, contain enough water to cover the entire body of an average-sized person; based on a mikveh with the dimensions of 3 cubits deep, 1 cubit wide, and 1 cubit long, the necessary volume of water was estimated as being 40 se'ah of water. The exact volume referred to by a seah is debated, and classical rabbinical literature specifies only that it is enough to fit 144 eggs; most Orthodox Jews use the stringent ruling of the Avrohom Yeshaya Karelitz, according to which one seah is 14.3 litres, and therefore a mikveh must contain approximately 575 litres . This volume of water could be topped up with water from any source, but if there were less than 40 seahs of water in the mikveh, then the addition of 3 or more pints of water from an unnatural source would render the mikveh unfit for use, regardless of whether water from a natural source was then added to make up 40 seahs from a natural source; a mikveh rendered unfit for use in this way would need to be completely drained away and refilled from scratch.

Securities Exchange Act of 1934

The Securities Exchange Act of 1934 (also called the Exchange Act, '34 Act, or 1934 Act) (Pub.L. 73–291, 48Stat.881, enacted June6, 1934, codified at 15 U.S.C.§78a et seq.) is a law governing the secondary trading of securities (stocks, bonds, and debentures) in the United States of America. A landmark of wide-ranging legislation, the Act of '34 and related statutes form the basis of regulation of the financial markets and their participants in the United States. The 1934 Act also established the Securities and Exchange Commission (SEC), the agency primarily responsible for enforcement of United States federal securities law.

Companies raise billions of dollars by issuing securities in what is known as the primary market. Contrasted with the Securities Act of 1933, which regulates these original issues, the Securities Exchange Act of 1934 regulates the secondary trading of those securities between persons often unrelated to the issuer, frequently through brokers or dealers. Trillions of dollars are made and lost each year through trading in the secondary market.

Bottom (technical analysis)

According to some technical analysis theories, the first low signifies the pressure from selling was greater than the pressure from buying. The second lower low suggests that selling still had more pressure than the buying. The third higher low suggests that buying pressure will not let prices fall as low as the previous low. This turning point from selling pressure to buying pressure is called a bottom.

Valley

A valley is a low area between hills, often with a river running through it.

In geology, a valley or dale is a depression that is longer than it is wide. The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of these two main types or a mixture of them, (at least) with respect to the cross section of the slopes or hillsides.

Valley terminology

A valley in its broadest geographic sense is also known as a dale. A valley through which a river runs may also be referred to as a vale. A small, secluded, and often wooded valley is known as a dell or in Scotland as a glen. A wide, flat valley through which a river runs is known in Scotland as a strath. A mountain cove is a small valley, closed at one or both ends, in the central or southern Appalachian Mountains which sometimes results from the erosion of a geologic window. A small valley surrounded by mountains or ridges is sometimes known as a hollow. A deep, narrow valley is known as a cwm (also spelled combe or coombe). Similar geological structures, such as canyons, ravines, gorges, gullies, and kloofs, are not usually referred to as valleys. See also: "chine". A valley formed by erosion is called an erosional valley; a valley formed by geologic events such as drop faults or the rise of highlands is called a structural valley.

The Economist

The Economist is an English language weekly newspaper owned by the Economist Group and edited in offices based in London. Continuous publication began under founder James Wilson in September 1843. For historical reasons, The Economist refers to itself as a newspaper, but each print edition appears on small glossy paper like a news magazine. In 2006, its average weekly circulation was reported to be 1.5 million, about half of which were sold in the United States.

The publication belongs to The Economist Group. It is 50% owned by private investors and 50% by Exor, the Agnelli holding company, and the Rothschild banking family of England. Exor and the Rothschilds are represented on the Board of Directors. A board of trustees formally appoints the editor, who cannot be removed without its permission. Although The Economist has a global emphasis and scope, about two-thirds of the 75 staff journalists are based in the City of Westminster, London. As of March 2014, the Economist Group declared operating profit of £59m. Previous major shareholders include Pearson PLC.

Deep-sea mining could transform the globe

Gold alone found on the sea floor is estimated to be worth $150 trn. But the cost to the planet of extracting it could be severe.

Deep-sea mining could transform the globe

Gold alone found on the sea floor is estimated to be worth $150 trn. But the cost to the planet of extracting it could be severe.

TechKnow - Deep sea gold rush

Oceans cover 70 percent of the earth's surface, but only a fraction of the undersea world has been explored.
On this episode of TechKnow, Phil Torres joins a team of scientists on a special expedition to explore and uncover the mysteries at the bottom of the ocean floor.
"What we are doing is similar to astronauts and planetary scientists just trying to study life on another planet," says BethOrcutt, a senior research scientist.
The journey begins in Costa Rica aboard the R/VAtlantis, a research vessel operated by the Woods Hole Oceanographic Institution. From there, Phil gets the chance to take a dive with Alvin, a deep-water submersible capable of taking explorers down to 6,000 metres (20,000 feet) under the sea.
Commissioned in 1964, Alvin has a celebrated history, locating an une...

How a Canadian company will mine the sea bed near Papua New Guinea

Canadian mining company Nautilus Minerals has reached an agreement with the government of Papua New Guinea to begin mining an area of seabed believed to be rich in gold and copper ores, according to the BBC.
Under the terms of the agreement, Papua New Guinea will contribute $120 million to the operation and receive a 15 percent share in the mine.
Environmentalists say the mine will devastate the area and cause long-lasting damage to the environment.
The BBC reports that "the mine will target an area of hydrothermal vents where superheated, highly acidic water emerges from the seabed, where it encounters far colder and more alkaline seawater, forcing it to deposit high concentrations of minerals."
The report continues:
The result is that the seabed is formed of ores that are far ric...

Sea bed mining scraping the bottom of the barrel

Out feature story this week takes us on a rather sobering underwater expedition into the dark world of seabed phosphate mining. The deep ocean floor, admittedly, is not a habitat we generally give much thought to. But in mankind’s quest for resources and mineral wealth, companies have now turned to this relatively unexplored region, and its phosphates they’re after, a resource in relatively limited supply on Earth. Is the supply of phosphates really so limited that it’s worth scraping our ocean bed completely bare? With our global seas, sea life and climate already in serious trouble, this action certainly seems like a bridge too far. Bertus went to see if he could get to the bottom of this matter.

Your future tech may rely on deep-sea mining

As the demand grows for the metals that power electronics, we may have to look farther and farther for mining opportunities. The next big mining frontier is the deep sea: along the seafloor, mysterious vents shoot scalding hot fluid into the ocean. These vents are a haven for miraculous and unique sea life, but they’re also home to highly concentrated (and very valuable) metals. What happens if we decide that the metals are worth more than the life?

Diving into the Philippines' dangerous, underwater mines

Filipino divers disappear into water as opaque as chocolate milk as they blindly dig in search of gold trapped in muddy sediment. It's risky business: As miners go deeper, underwater tunnels could collapse or the compressor that provides air may fail. Hari Sreenivasan reports on a dangerous venture undertaken by adults and kids.

Oceans cover 70 percent of the earth's surface, but only a fraction of the undersea world has been explored.
On this episode of TechKnow, Phil Torres joins a team of scientists on a special expedition to explore and uncover the mysteries at the bottom of the ocean floor.
"What we are doing is similar to astronauts and planetary scientists just trying to study life on another planet," says BethOrcutt, a senior research scientist.
The journey begins in Costa Rica aboard the R/VAtlantis, a research vessel operated by the Woods Hole Oceanographic Institution. From there, Phil gets the chance to take a dive with Alvin, a deep-water submersible capable of taking explorers down to 6,000 metres (20,000 feet) under the sea.
Commissioned in 1964, Alvin has a celebrated history, locating an unexploded hydrogen bomb off the coast of Spain and exploring the famous RMS Titanic in the 1980s.
Alvin and its first female pilot, CindyVan Dover, were the first to discover hydrothermal vents, which are underwater springs where plumes of black smoke and water pour out from underneath the earth's crust. The vents were inhabited by previously unknown organisms that thrived in the absence of sunlight.
After 40 years of exploration, Alvin got a high-tech upgrade. The storied submersible is now outfitted with high-resolution cameras to provide a 245-degree viewing field and a robotic arm that scientists can use to pull samples of rock and ocean life to then study back on land.
But scientists are not the only ones interested in the ocean. These days the new gold rush is not in the hills, it is in the deep sea. For thousands of years miners have been exploiting the earth in search of precious metals. As resources on dry land are depleted, now the search for new sources of metals and minerals is heading underwater.
The NationalOceanic and Atmospheric Administration's national ocean service estimates that there is more than $150tn in gold waiting to be mined from the floor of the world's oceans.
"The industry is moving very, very fast. They have far more financial resources than the scientific community," says Cindy Van Dover, Alvin's first female pilot and Duke University Oceanography Professor.
Seabed mining is still in the planning stages, but Nautilus Minerals, a Canadian mining company, says it has the technology and the contracts in place with the island nation of Papua New Guinea to start mining in its waters in about two years.
What is the future of seabed mining? And what are the consequences of seabed mining for the marine ecosystems? Can science and industry co-exist and work together on viable and sustainable solutions?

Mike Johnston, chief executive of Nautilus Minerals told the BBC "that a temperature probe left in place for 18 months was found to have 'high grade copper all over it'."
Nautilus announced in April that it had completed its bulk cutter, the first component of its Seafloor ProductionTools system, which will be used to mine the seabed.
Nautilus also approximately 500,000 square kilometres of "highly prospective exploration acreage" in Papua New Guinea, the Solomon Islands, Fiji, Vanuatu and Tonga, as well as in international waters in the eastern Pacific, the company said in a press release.

Deep down, way deep down, there's something stirring - something very, very valuable.
It's a race to the bottom - to the bottom of the oceans. It is Deep Sea Mining. As deep as 5000 metres, maybe more, lie a host of materials critical for modern society, from smartphones to electric cars to green energy. But how can be it be mined without ruining another beautiful, so-far untouched - yet valuable part of our planet?
Joining us on skype from Kingston, JamaicaMichaelLodge, Secretary-General at the International Seabed Authority; from Washington DC, Conn Nugent, ProjectDirector of Seabed Mining Project at the Pew Charitable Trusts; Regan Drennan, Research Assistant at UK Seabed Resource who studies the biodiversity of the ocean floor; Charlotte Middlehurst, a Contributing Editor at ChinaDialogue, focusing on China's growing interest in deep sea mining.
Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRTWorld.

The ocean covers 70% of our planet. The deep-sea floor is a realm that is largely unexplored, but cutting-edge technology is enabling a new generation of aquanauts to go deeper than ever before.
Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7
Beneath the waves is a mysterious world that takes up to 95% of Earth's living space. Only three people have ever reached the bottom of the deepest part of the ocean. The deep is a world without sunlight, of freezing temperatures, and immense pressure. It's remained largely unexplored until now.
Cutting-edge technology is enabling a new generation of aquanauts to explore deeper than ever before. They are opening up a whole new world of potential benefits to humanity. The risks are great, but the rewards could be greater. From a vast wealth of resources to clues about the origins of life, the race is on to the final frontier
The Okeanos Explorer, the American government state-of-the-art vessel, designed for every type of deep ocean exploration from discovering new species to investigating shipwrecks. On board, engineers and scientists come together to answer questions about the origins of life and human history.
Today the Okeanos is on a mission to investigate the wreck of a World War one submarine. EngineerBobby Moore is part of a team who has developed the technology for this type of mission.
The “deep discover”, a remote operating vehicle is equipped with 20 powerful LED lights and designed to withstand the huge pressure four miles down. Equivalent to 50 jumbo jets stacked on top of a person
While the crew of the Okeanos send robots to investigate the deep, some of their fellow scientists prefer a more hands-on approach. DoctorGreg stone is a world leading marine biologist with over 8,000 hours under the sea. He has been exploring the abyss in person for 30 years.
The technology opening up the deep is also opening up opportunity. Not just to witness the diversity of life but to glimpse vast amounts of rare mineral resources. Some of the world's most valuable metals can be found deep under the waves. A discovery that has begun to pique the interest of the global mining industry.
The boldest of mining companies are heading to the deep drawn by the allure of a new Gold Rush. But to exploit it they're also beating a path to another strange new world. In an industrial estate in the north of England, SMD is one of the world's leading manufacturers of remote underwater equipment. The industrial technology the company has developed has made mining possible several kilometers beneath the ocean surface.
With an estimated 150 trillion dollars’ worth of gold alone, deep-sea mining has the potential to transform the global economy.
With so much still to discover, mining in the deep ocean could have unknowable impact. It's not just life today that may need protecting; reaching the deep ocean might just allow researchers to answer some truly fundamental questions. Hydrothermal vents, hot springs on the ocean floor, are cracks in the Earth's crust. Some claim they could help scientists glimpse the origins of life itself.
We might still be years away from unlocking the mysteries of the deep. Even with the latest technology, this kind of exploration is always challenging. As the crew of the Okeanos comes to terms with a scale of the challenge and the opportunity that lies beneath, what they and others discover could transform humanity's understanding of how to protect the ocean.
It's the most hostile environment on earth, but the keys to our future may lie in the deep.

Filipino divers disappear into water as opaque as chocolate milk as they blindly dig in search of gold trapped in muddy sediment. It's risky business: As miners go deeper, underwater tunnels could collapse or the compressor that provides air may fail. Hari Sreenivasan reports on a dangerous venture undertaken by adults and kids.

GoPro footage of what it is like to dredge in fairly easy conditions; shallow (2-4 ft.) material, shallow water, and moderate current. When I move further out into the river the current will be much more powerful making everything more difficult.

TechKnow - Deep sea gold rush

Oceans cover 70 percent of the earth's surface, but only a fraction of the undersea world has been explored.
On this episode of TechKnow, Phil Torres joins a team of scientists on a special expedition to explore and uncover the mysteries at the bottom of the ocean floor.
"What we are doing is similar to astronauts and planetary scientists just trying to study life on another planet," says BethOrcutt, a senior research scientist.
The journey begins in Costa Rica aboard the R/VAtlantis, a research vessel operated by the Woods Hole Oceanographic Institution. From there, Phil gets the chance to take a dive with Alvin, a deep-water submersible capable of taking explorers down to 6,000 metres (20,000 feet) under the sea.
Commissioned in 1964, Alvin has a celebrated history, locating an unexploded hydrogen bomb off the coast of Spain and exploring the famous RMS Titanic in the 1980s.
Alvin and its first female pilot, CindyVan Dover, were the first to discover hydrothermal vents, which are underwater springs where plumes of black smoke and water pour out from underneath the earth's crust. The vents were inhabited by previously unknown organisms that thrived in the absence of sunlight.
After 40 years of exploration, Alvin got a high-tech upgrade. The storied submersible is now outfitted with high-resolution cameras to provide a 245-degree viewing field and a robotic arm that scientists can use to pull samples of rock and ocean life to then study back on land.
But scientists are not the only ones interested in the ocean. These days the new gold rush is not in the hills, it is in the deep sea. For thousands of years miners have been exploiting the earth in search of precious metals. As resources on dry land are depleted, now the search for new sources of metals and minerals is heading underwater.
The NationalOceanic and Atmospheric Administration's national ocean service estimates that there is more than $150tn in gold waiting to be mined from the floor of the world's oceans.
"The industry is moving very, very fast. They have far more financial resources than the scientific community," says Cindy Van Dover, Alvin's first female pilot and Duke University Oceanography Professor.
Seabed mining is still in the planning stages, but Nautilus Minerals, a Canadian mining company, says it has the technology and the contracts in place with the island nation of Papua New Guinea to start mining in its waters in about two years.
What is the future of seabed mining? And what are the consequences of seabed mining for the marine ecosystems? Can science and industry co-exist and work together on viable and sustainable solutions?

How a Canadian company will mine the sea bed near Papua New Guinea

Canadian mining company Nautilus Minerals has reached an agreement with the government of Papua New Guinea to begin mining an area of seabed believed to be rich in gold and copper ores, according to the BBC.
Under the terms of the agreement, Papua New Guinea will contribute $120 million to the operation and receive a 15 percent share in the mine.
Environmentalists say the mine will devastate the area and cause long-lasting damage to the environment.
The BBC reports that "the mine will target an area of hydrothermal vents where superheated, highly acidic water emerges from the seabed, where it encounters far colder and more alkaline seawater, forcing it to deposit high concentrations of minerals."
The report continues:
The result is that the seabed is formed of ores that are far richer in gold and copper than ores found on land.
Mike Johnston, chief executive of Nautilus Minerals told the BBC "that a temperature probe left in place for 18 months was found to have 'high grade copper all over it'."
Nautilus announced in April that it had completed its bulk cutter, the first component of its Seafloor ProductionTools system, which will be used to mine the seabed.
Nautilus also approximately 500,000 square kilometres of "highly prospective exploration acreage" in Papua New Guinea, the Solomon Islands, Fiji, Vanuatu and Tonga, as well as in international waters in the eastern Pacific, the company said in a press release.

Deep Sea Mining: Searching for the Next Mineral Boom

Deep down, way deep down, there's something stirring - something very, very valuable.
It's a race to the bottom - to the bottom of the oceans. It is Deep Sea Mining. As deep as 5000 metres, maybe more, lie a host of materials critical for modern society, from smartphones to electric cars to green energy. But how can be it be mined without ruining another beautiful, so-far untouched - yet valuable part of our planet?
Joining us on skype from Kingston, JamaicaMichaelLodge, Secretary-General at the International Seabed Authority; from Washington DC, Conn Nugent, ProjectDirector of Seabed Mining Project at the Pew Charitable Trusts; Regan Drennan, Research Assistant at UK Seabed Resource who studies the biodiversity of the ocean floor; Charlotte Middlehurst, a Contributing Editor at ChinaDialogue, focusing on China's growing interest in deep sea mining.

The deep ocean is the final frontier on planet Earth

Watch the latest in the Ocean series - What sharks reveal about the state of the Ocean: https://youtu.be/6xz1mxppMhY
The ocean covers 70% of our planet. The deep-sea floor is a realm that is largely unexplored, but cutting-edge technology is enabling a new generation of aquanauts to go deeper than ever before.
Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7
Beneath the waves is a mysterious world that takes up to 95% of Earth's living space. Only three people have ever reached the bottom of the deepest part of the ocean. The deep is a world without sunlight, of freezing temperatures, and immense pressure. It's remained largely unexplored until now.
Cutting-edge technology is enabling a new generation of aquanauts to explore deeper than ever before. They are opening up a whole new world of potential benefits to humanity. The risks are great, but the rewards could be greater. From a vast wealth of resources to clues about the origins of life, the race is on to the final frontier
The Okeanos Explorer, the American government state-of-the-art vessel, designed for every type of deep ocean exploration from discovering new species to investigating shipwrecks. On board, engineers and scientists come together to answer questions about the origins of life and human history.
Today the Okeanos is on a mission to investigate the wreck of a World War one submarine. EngineerBobby Moore is part of a team who has developed the technology for this type of mission.
The “deep discover”, a remote operating vehicle is equipped with 20 powerful LED lights and designed to withstand the huge pressure four miles down. Equivalent to 50 jumbo jets stacked on top of a person
While the crew of the Okeanos send robots to investigate the deep, some of their fellow scientists prefer a more hands-on approach. DoctorGreg stone is a world leading marine biologist with over 8,000 hours under the sea. He has been exploring the abyss in person for 30 years.
The technology opening up the deep is also opening up opportunity. Not just to witness the diversity of life but to glimpse vast amounts of rare mineral resources. Some of the world's most valuable metals can be found deep under the waves. A discovery that has begun to pique the interest of the global mining industry.
The boldest of mining companies are heading to the deep drawn by the allure of a new Gold Rush. But to exploit it they're also beating a path to another strange new world. In an industrial estate in the north of England, SMD is one of the world's leading manufacturers of remote underwater equipment. The industrial technology the company has developed has made mining possible several kilometers beneath the ocean surface.
With an estimated 150 trillion dollars’ worth of gold alone, deep-sea mining has the potential to transform the global economy.
With so much still to discover, mining in the deep ocean could have unknowable impact. It's not just life today that may need protecting; reaching the deep ocean might just allow researchers to answer some truly fundamental questions. Hydrothermal vents, hot springs on the ocean floor, are cracks in the Earth's crust. Some claim they could help scientists glimpse the origins of life itself.
We might still be years away from unlocking the mysteries of the deep. Even with the latest technology, this kind of exploration is always challenging. As the crew of the Okeanos comes to terms with a scale of the challenge and the opportunity that lies beneath, what they and others discover could transform humanity's understanding of how to protect the ocean.
It's the most hostile environment on earth, but the keys to our future may lie in the deep.

Sea bed mining scraping the bottom of the barrel

Out feature story this week takes us on a rather sobering underwater expedition into the dark world of seabed phosphate mining. The deep ocean floor, admittedly, is not a habitat we generally give much thought to. But in mankind’s quest for resources and mineral wealth, companies have now turned to this relatively unexplored region, and its phosphates they’re after, a resource in relatively limited supply on Earth. Is the supply of phosphates really so limited that it’s worth scraping our ocean bed completely bare? With our global seas, sea life and climate already in serious trouble, this action certainly seems like a bridge too far. Bertus went to see if he could get to the bottom of this matter.

Your future tech may rely on deep-sea mining

As the demand grows for the metals that power electronics, we may have to look farther and farther for mining opportunities. The next big mining frontier is the deep sea: along the seafloor, mysterious vents shoot scalding hot fluid into the ocean. These vents are a haven for miraculous and unique sea life, but they’re also home to highly concentrated (and very valuable) metals. What happens if we decide that the metals are worth more than the life?
Thank you to OceanExplorationTrust for allowing us to use clips from their deep sea footage. You can follow their next expedition season here: www.nautiluslive.org
